Keanu Reeves playing another surfer?

As reported here early this month, rumors are flying that the Silver Surfer and Galactus will be the villains in the forthcoming Fantastic Four sequel. As a result - and because rumors are the lifeblood of the internets - people immediately started to discuss who might play the roles (assuming, of course, that the phase one rumors are true). Names like The Rock, Vin Diesel, and Wesley Snipes have been associated with the Silver Surfer in the past, but the one that seems to be in the forefront of discussions this time belongs to a much smaller man: Keanu Reeves. Supposedly Reeves is being considered for the role by people with actual power, and not just by fanboys. I'm a little confused about how, if those three, muscle-bound dudes are appropriate body types, Reeves can actually play the part - perhaps it's his Point Break surfing experience that gives him the edge.
